Embodiment Construction

[0032]As shown in FIG. 1, an oven 20, which may be what is typically referred to as a “toaster oven,” has a manual control or actuator 22 that may be a knob or lever as shown to be used for changing the position of a heating element 24. The oven 20 has an outer casing 26. A door 28 has a clear window 29 revealing the interior chamber or heating compartment 30. Typical controls are shown at 32 and do not form a part of this invention. Through an internal mechanical construction shown in FIGS. 3-6, the heating element 24 can be moved up, as shown in FIG. 1, or down, as shown in FIG. 2, depending on the positioning of the actuator 22.

[0033]Both ends of the heating element 24 connect to a linkage system 34. The linkage system 34 includes a first linkage 36 on the actuator side of the oven (FIGS. 3 and 4) connected to a second remote linkage 38 on the remote side of the oven (FIGS. 5 and 6) by a motion transfer bar 39. The motion transfer bar 39 transfers the rotational motion of the act...

Abstract

A food heating or cooking appliance has at least one electrical heating element within its interior that is adjustable in position so as to be able to be moved close to thin or small food items under the control of a manually actuated control. A separator plate that extends across the interior chamber of the appliance from side to side and from front to back is movable with the heating element to enable adjustment of the volumetric size of the cooking chamber containing the heating element and the food to be heated or cooked. A manual actuator, a knob or lever, for example, moves the heating element and the separator plate through a motion transfer bar that extends across the width of the appliance and is attached to a linkage on each side of the appliance to communicate movement to a pair of movable supports supporting the rod-like heating element at each of its ends and the separator plate at opposite edges.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. provisional patent application Ser. No. 60 / 791,674 filed on Apr. 12, 2006 in the names of Wilson (Wing Shun) Lau, Wing Hei Cho and Charles (U Fung) Lam, and entitled “Reconfigurable Heating Element,” and from U.S. provisional patent application Ser. No. 60 / 813,501 filed on Jun. 13, 2006, in the names of Wilson (Wing Shun) Lau and Charles (U Fung) Lam, and entitled “Electric Oven with Reconfigurable Heater Element and Separator Plate.” Both applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to an electrical food heating or cooking apparatus or appliance and more specifically to such an apparatus that is reconfigurable to better cook a variety of food items of various sizes.BACKGROUND OF THE INVENTION[0003]In the conventional oven or toaster oven, the heating elements are fixed in location and the heating compartment is fixed in size. When the user ...
